Why Choose 12mm Mini Open Mesh GRP Decking?
Mini Open Mesh GRP Marina Decking features a 12mm × 12mm open mesh design combined with a gritted anti-slip surface, providing an excellent balance of underfoot comfort, drainage, and structural strength. Designed for demanding marine and leisure environments, it delivers reliable slip resistance in wet, oily, and icy conditions.
The 12mm aperture size helps prevent larger objects from falling through while still allowing water, light, and debris to pass freely. Lightweight yet structurally strong, 12mm mini open mesh GRP decking is a low-maintenance alternative to timber and steel, making it ideal for pontoons, marina walkways, access gangways, and pedestrian platforms.
Compared to micro mesh decking, the 12mm mini open mesh option offers increased strength and load capability while maintaining excellent drainage and slip resistance.
